Product Details

DFC’s GEOSPEC rotor line is machined to OE-style tolerances and finished to help resist rust better than conventional paint or zinc coatings. The rotors are processed dry and ready to install, which reduces prep time during brake service. The 5000 Advanced pads are post cured and scorched to reduce initial break-in time, while the included shims help control brake noise and vibration. The hardware kit is engineered for form, fit, and function on the rear axle, supporting consistent caliper movement and even pad wear.

This part number 4512-63118 is a practical choice for Mercedes-Benz rear brake service where coated rotors and ceramic pads are preferred for cleaner operation and corrosion resistance. It is a direct-fit style solution for rear brake jobs on the Mercedes-Benz 300D, 300SD, 300SEL, 300SE, 380SEL, and related chassis listed below.

What It Helps Address

• Rear brake noise from worn pads or fatigued hardware
• Uneven pad wear caused by corroded or weak hardware
• Longer stopping distances from worn rotor and pad surfaces
• Rust buildup on exposed rotor surfaces
• Brake vibration related to rotor finish or pad contact issues
